"Herbert William Conn (January 10, 1859 - April 18, 1917) was a bacteriologist and educator from the United States. Born in Fitchburg, Massachusetts, the son of Reuben Rice Conn and Harriot Elizabeth, he contracted rheumatic disease as a child and had to be removed from public school due to his bad health. Instead, he attended Cushing Academy, a private school in Ashburnham, Massachusetts, before enrolling at Boston University and graduating second in his class with an A.B. in 1881. In 1881, he enrolled in graduate school at Johns Hopkins University, where he earned his Ph.D. in animal morphology, physiology, and histology in 1884 with a thesis titled ""Life-history of Thalassema,"" for which he received the Boston Society of Natural History's Walker award. He married Julia M. Joel in August 1885, and the pair had two children, including soil bacteriologist and stain expert Harold J. Conn. Following graduation, Conn joined the faculty of Wesleyan University as a biology instructor, eventually becoming a biology professor and founding the university's biology department in 1887. For the rest of his career, he would hold the chair of biology. The same year, he was appointed acting director of the zoology department at Martha's Vineyard Summer Institute."
